The present disclosure relates to a corrosion inhibitor formulation comprising: a) at least one quaternary ammonium salt; b) at least one fatty acid methyl ester; c) at least one viscosity reducing agent; and d) at least one solubilizing agent, wherein the at least one quaternary ammonium salt to the at least one fatty acid methyl ester weight ratio is in the range of 1:0.2-1:5.0. The instant disclosure further relates to the process of preparation of the corrosion inhibitor formulation.

Formulation for corrosion inhibition

The present disclosure provides a bis-quaternary ammonium salt of Formula I wherein A is selected from O, NH, S, C(O), C(NH) or C(S); Rand Rare independently selected from Calkyl or H; Ris Calkyl, Caralkyl or Callyl; Xis selected from chloro, bromo, iodo, hydroxide, nitrate or sulphate; and n and m are independently 1 to 6. Furthermore, a corrosion inhibition formulation comprising said bis-quaternary ammonium salt is revealed. Also, convenient processes for the preparation of the salt of Formula I and the formulation are provided.
